i ro' ALL wHoM'rr MA1 ooNo'nRm Be it `lrnown that I, Hanni BAILEY, ofthe city, county, andState of New York, have invented o new and usefulImprovement in Steam-Engines, of which the following is a full, clear,and exactdescription, reference being had to the accompanying drawing,forming' part of this sp'ecication, and ih which; A' A i Figure 1represents a longitudinal section of esteem-engine, in part constructedaccording to my imprevemeiit, and l .i s I A Y Figure 2 a transversesection, taken aus indicated by'the line z :ein iig.1.

. Similar letters of reference indicato corresponding parts.

This improvement has eferenceamore-particularly, to that description ,of'engines in whiohfa-:evolving i crank, with its operating pitman, i'senclosed vithn a steam or waterftight head, arranged to forman e'xten-,sion, asit were, from the'one endof thecylinder,-in which the piston,to-whichthe pitman is directly pivoted, works, as secured by LettersPatent,(No.h62,920,) issued March 19, 1861; 'andmyinvention consists, incom(v b'ination with suchannrrangemcnt, in giving a close, orcomparatively close, character ytol the 'end of the cyl-- inder thatconnects with the hollow head, as referred to,by providing the sam'ewith a dividing piece, tted with -a loose orfree tra'nivers e slide,having ol rocking joint-piece or block, through which-the pitman passes,and

f'the action of lwhich, combined yth the transverse motion of the-slide,provides' for the play of the pitman in a comparatively close mannerthroughit, said slide forming a division, as it were, betweentheecylinder an'd head, which, combined, enclose the crank, pitmna',undpiston. .v

Referringv t. the accompanyingtdmwing, wh-'chrepreeentetheentioneapplied-to `at,la5ix:ixiintal,steamengine, A isthe'bedeplate of the engine, and B its cylinder, ivlhieh -lnay`beiittedwith any suitable-valve for admitting steamto and exhausting it fromalternately'opposite ends, to reciprocatea piaton,-C. Connected, as' auextension-,box or chamber, with-the forward end of the cylinder, i'l thelsteam or water-tight head D, prefer. c bly of a shape corresponding `tothe travel of-the'pi'truen E, and within which the main shaft Fprojects, and carries, inside of said head, a crank or dieli, G,provided with a wrst-pin, e, toi-which the pitm'an E is attached, nt-itsouter end, its inner end being pivotefl to the piston C, preferablywithin the-body of the latter;

' Such an arrangement of parts not only dispenses with a piston-rod, but-forms a steudyfworlring and conn pact formof engine, with piston,pitmanfand crank alike concealed from view and inj'ury. It, however', isopen to the objection, 'here theforwardV end of the cylinder B is inuninterrupted communication with the steam- -h'jad -D, of a certainlos's or 'waste of steam, when exhausting from the en d with ,which thehead connects, by steam contained therein also passing od' with'thesteam-from the cylinder. L v

To obviate thisanid yet retnin'the same arrangement of parte, in-allessentialrespcc'ts, lI c losepor rather partly close, the forward r endof the cylinder, or end of the head D, against which it abats, stillmaking said head a steam or water-tight box-shaped extension to suchcylinder-end, and provide the division, la, no formed between'theinterior of the cylinder and headhvith a loose or free slide,', having atraverse, transversely to the motion' ofthe piston, and covering-anoblong slot or opening, c, riiu'fle in the divison'b, also working utits ends in pockets or chambers d, so as to enclose thesame in coinnionwith the ot'herlworking parte. This nliilell has an opening, e, madethrough it, 'for the play. and passage ofthe pitnian, whichopc'nngiscoveed by a rocking' joint-piece 'or' block, I, pivoted, nsatf, to the slide, and oi'- curved form on its face, to tit acorrespondinglyshaped seat in the slide, the pitma'n, which ispreferably made-round, working in a elosehut free manner through thoblock or joint-piece I'. By the combinodnction' of the slide HI androcking block l, the pitman has free passage andrswing or play, ina'sufciently stcam-tight manner, without the aid'of'a smiling-box; but,inasmuch as the head D forms a steam or` water-tight enclosure to,-orextension of, the forward cylinder-end, as it \."l'e, it is by no--mcansnece'snarythat theelide H should Vbe otherwlsethan a-good working fit,and pinching4 A to it may, if desired, be dispensed with, so that thefree swing and play of the pitman will in,nov1ise, or atleast notmnterially,b'e interfered with by it. Y "l,- v

t "The invention' may also bc applied to work' oser in connection -witha pump, by-ina'hing the shaft F, the

,driver to the pistonfand providing the cylinderwith suitable valves andsuction and dischargepipce.' 't

What is'her'e claimed, and-desired tobc secured by Letters Patent, is-

-The combination, wit-h thc cylinder Band head D, forl enclosedoperation within them ofthe piston, pitman, and' crank, described, ofthe interposed slide H, with its rocking joint-piece or block I, allforaction together,l essentially us herein `set forth. I i
